After successful defibrillation, echocardiography revealed hypertrophic cardiomyopathy associated with left ventricular outflow tract obstruction. Normal echocardiographic cardiac structure and function were reported 11 years ago. This case emphasises the importance of regular follow-up in patients with congenital disorders in which cardiac manifestations might develop in early adulthood or later.eninfo:eu-repo/semantics/closedAccessArticle234221205420Q323321WOS:000287539400023Q4
